　　背景介紹

　　Background

　　本案例利用電阻層析成像和三維打印技術對旋噴灌注樁的三維幾何形態(tài)進行物理模擬和實驗監(jiān)測。首先，通過使用三維打印技術對碳晶導電增強材料進行類旋噴樁的模型構造，其次使用電阻層析成像系統(tǒng)對固化作用后的類旋噴樁進行重構建模，利用粉末三維打印技術構建小型加固試樣進行加固體幾何形態(tài)和力學特性研究。通過實驗研究，得到了室內(nèi)工況下旋噴灌注樁三維加固形態(tài)和加固力學特性的物理實驗數(shù)據(jù)，探索了電阻層析成像和三維打印技術在巖土加固研究中的應用，為后續(xù)的三維加固形態(tài)數(shù)學建模和數(shù)值模擬分析提供了初步的驗證數(shù)據(jù)。

　　This case utilizes electrical resistance tomography and 3D printing technology to physically simulate and experimentally monitor the three-dimensional geometric shape of rotary sprinkler irrigation piles. Firstly, a three-dimensional printing technology was used to construct a model of carbon crystal conductive reinforcement material similar to rotary jet grouting piles. Secondly, a resistance tomography system was used to reconstruct and model the solidified rotary jet grouting piles. Finally, a small reinforced sample was constructed using powder three-dimensional printing technology to study the solid geometry and mechanical properties. Through experimental research, physical experimental data on the three-dimensional reinforcement morphology and mechanical characteristics of rotary jet grouting piles under indoor working conditions were obtained. The application of electrical resistance tomography and three-dimensional printing technology in geotechnical reinforcement research was explored, providing preliminary validation data for subsequent mathematical modeling and numerical simulation analysis of three-dimensional reinforcement morphology.
